Hw99 stripdown

[Kalibrgun]

Right so the 99 seemed a bit flippy and touch twangy for what I thought acceptable compared to others I've had in the past. But if advice from the forum and YouTube I thought I'd give it a go cleaning and re greasing myself. Stripped the gun a doddle but what a mess sticky black grease everywhere spring fell apart dropping it out and piston deal looks like it's seen better days but may clean ? Can't attach pics for some reason either not sure why I can attatch them in the sales but not here ?

So, it was twangy (requiring the services of a properly fitting guide) and the spring and seal are needing replacing. So a kit is required.

Some very good ones out there which will improve things - any of the following will be good - V-Mach, SFS, Tinbum, Welsh Willy, wonkydonky, Vortek. Listed in no order of preference.

For what it costs, replace the breech seal too whilst you're at it and bear in mind that not all of the kits include the piston seal.

A good de-grease, check, gentle polish and fitting the kit with the correct amount of lube will result in a much more nicely mannered little rifle. You were getting good results beforehand; it'll be even better once correctly fettled.

I still can get my head around how it was firing with a broken spring I wouldn't of thought it there was no twang just a bit jumpy

Just got back from the shop where I got the rifle he's ordered a new spring but is a titan they're the ones he will order nothing else so I've left the action and barrel with him and said I want the spring dressing properly and will need shortening. He's going to fit it all back together and set around 10.8-11 ftlb for me. I will be stripping it when it comes back to see what sort of job has been done but he's using the std guide and a slip washer so well see what it's like on return. From what I've read I think it's going to be a snappy little get

Not necessarily snappy, depending which of the Titans he uses and adjusts accordingly.

The standard HW synthetic guide is actually really, really good. A good and strong two-piece design. If it fits the selected spring properly, no need to look any further.

If he finishes the spring off properly, and with the slip washer, all might be very, very good. I'd still always prefer a top hat at the front end of the spring, giving more support and an extra bearing surface with a polished steel or synthetic washer ahead of it. These days a spring just doesn't seem properly dressed without one!

Although a lightweight, the 99 isn't obliged to be snappy. Indeed, in .22 they can shoot very demurely at close to legal limit power. With a correct set-up and running around 11 it should be extremely nice to shoot.

Enjoy once back; I'm sure you will.

It's a no1 spring that he had listed for the 99 if it's no good at least hes tried sorting it but I'm getting a kit off tinbum so will go the maxi kit with oem spring I enjoyed stripping it but know how to do it now so will have it apart again I want to mirror polish everything up and get it as sweet as poss. Even thinking of glided piston etc when the funds allow
